A client has recently been diagnosed with type II endometrial cancer and will be treated with brachytherapy. What statement by the client indicates a need for further education on this treatment?

Rationale: A. During brachytherapy (internal radiation), the radioactive source is placed inside or near the tumor. Because the client emits radiation during this time, visitors and staff must limit exposure, and the client remains in isolation until the source is removed or the radiation decays. B. High-dose rate (HDR) brachytherapy sessions are typically short, lasting about 20–30 minutes per session. Low-dose rate treatments may require longer stays, but HDR is most common for endometrial cancer. C. This statement indicates a lack of understanding. During brachytherapy, the radioactive applicator must remain in precise position, so the client is required to remain on bedrest and avoid movement to prevent displacement of the radioactive source and exposure risk. D. These are potential complications of brachytherapy due to local tissue damage to the vagina, rectum, or bladder and should be reported immediately.
